FIGURE 10 - Orange meshes represent the behavior of the trilinear interpolant in the MC cases: 7.4.2, 10.1.2, 12.1.2, 13.5.2. The green meshes are the triangulation proposed by Chernyaev to approximate the isosurface inside the cube in each case.





The tunnel triangulation proposed by Chernyaev. Observe that in the proposed triangulation some triangles lie on the ambiguous faces of the grid cell.
